I believe before DHS can not revoke visas, and only the courts can?
But the recent Supreme Court ruling allows DHS, of which USCIS and CBP are part of, to revoke visas.

So if I understand this correctly before, CBP can deny visa entry but can not take away your visa and those denied entry can appeal to the courts?
But now, CBP can deny entry AND take away the visa at POE?
Is that the correct interpretation?
